Q = 2 \cdot π \frac{E}{δ E}

$Q = 2*pi E /( deltaE )$

(E) Energy

The Anelastic Attenuation Factor, also known as Seismic Quality Factor, quantifies the effects of anelastic attenuation on the seismic wavelet caused by fluid movement and grain boundary friction. As a seismic wave propagates through a medium, the elastic energy associated with the wave is gradually absorbed by the medium , eventually ending up as heat energy. This is known as absorption which will eventually cause the total disappearance of the seismic wave. The formula used is: $Q = 2 π \frac{E}{δ E}$ $Q=2piE/(deltaE)$ , where:

$E$ $E$ = Energy
$δ E$ $deltaE$ = change in energy
